Summary

FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.5.2-stable and 2.0.1-beta, file read handling in backend/pkg/indexing/indexingFiles.go resolves symbolic links through GetRealPath without confirming that the resolved target remains inside the source root and the user's authorized scope. Download, preview, media, OnlyOffice, and public-share read flows that enable FollowSymlinks can therefore serve an out-of-scope target through a reachable in-scope symlink. An authenticated user with download access can read server-accessible files outside the assigned scope, and a holder of a public share link can do the same without an account when the shared directory exposes such a symlink. This issue is fixed in 1.5.2-stable and 2.0.1-beta.
